"That's how lucky I'll see it this time."

I walked to the bus stop and waited for a while and found that the bus had not arrived yet.

"How long will it take for Sister Yinxing to arrive in the bus?"

A map appears in front of you to indicate where the bus has arrived, the time and speed, etc.

"The little master will arrive in two minutes."

"By the way, how much money do I have? But don't lose money, otherwise it will be bad if I owe the money."

"Little master, you still have 3682RMB in balance. The master sent you 3000RMB this morning."

At this time, the bus arrived and Liu Yu got on the bus without paying, because he knew that he got on the bus, so he started billing. When he arrived at the station and left the bus, the money would be automatically deducted.

When I arrived at the school, I walked through the fully automatic disinfection door and the machine security guard and entered the school.

There were five minutes left before class, and the students were wearing educational version of Nebula glasses one after another, and the teacher also entered the door with Nebula glasses.

"What students are going to talk about today is a cuboid cube and a multilateral body. You see that the object in front of you is a cube we have seen in the last class."

There was a cube floating on the table in front of Liu Yu's eyes. He could adjust the rotation. He rotated and counted it again. Why did it be the seven-sided side? Didn't he say six-sided side? This time he marked the corresponding number on each side he counted, and finally the right number was six-sided side.

The morning passed in a hurry. After lunch, Liu Yu wanted to go to the electronics hall.

After leaving school, "Sister Yinxing helps me get a taxi."

"Okay, there is a car more than 200 meters ahead, come here immediately."

A silver-white car stopped in front of Liu Yu, automatically lifted the car door, and Liu Yu went in.

There was no driver in this car, and Liu Yu was not surprised at all. He got in the car and said he would go to the electronics hall.

A female voice sounded in the car. After the navigation is loaded, please fasten your seat belt, abide by the safety law, and prepare to set off.

After a while, Liu Yu got out of the car, and his account was automatically deducted 20RMB.

When he walked into the electronics hall, he played VR games and watched VR movies. In the afternoon, he listened to the psychological counseling class taught by Miss Hatsune.

In the evening, Liu Yudian started chatting with Yx and clicked on friends nearby. He found a little brother who loved to play with him when he thought he was very much. However, he seemed to be the top scorer now, very powerful. "Little top scorer brother, can I ask you a question? Why did my father hate me as a virtual idol star when I grew up, what's the best for astronauts?"

The little top brother said patiently: "I will be at the space station in China in a few years. We do this to repay the cultivation of the motherland's motherland. Brother Liu Yu, you must learn to be grateful when you grow up, because it is not easy for Uncle Chang to raise you. Come on, study and grow up and become a pillar of society and the country!"

"Just like the little top brother, I will work hard to study." Liu Yu said sensiblely, with crystal tears hanging on the corners of his eyes. "Motherland needs me, my brother has to learn the knowledge of the space station. I will chat with Liu Yu when I come back." Liu Yu quit Penguin socializing, and the computer suddenly turned off. "I didn't press the close button, why did the computer turn off by itself?"

When Dad Chang walked into the room, he still said seriously: "Xiaoyu, it's so late, so I won't go to bed!" Liu Yu could no longer control his tears. He said sensiblely: "Dad, just like the little top-level brother said, I want to study hard, repay the motherland, and become an astronaut like the little top-level brother."

"Silly child, Dad doesn't ask you to be an astronaut. As long as you live a good life in the future, you will be satisfied." Dad Chang said with great satisfaction. Finally, Dad Chang's face became gentle like the spring breeze blowing on his face.

Two years later, Liu Yu achieved excellent results and successfully went to junior high school to a key junior high school in the district. His physics is outstanding among children of the same age, and this physical expertise makes the whole family proud of him.

At night, Liu Yu opened his future Nebula glasses and searched for an English word in Yx - Interconnection   of   all    things. "What a difficult English word, but it feels very interesting." Liu Yu used Yx translation and translated it out by machine. "Everything is connected." Liu Yu looked up at the starry sky. At this time, countless shining stars connected into a spectacular network. He knew that they were small satellites. With them, he could access the Internet.

Dividing line————

Warm applause rang out from the audience. After the applause ended, Zhang Yi came to the stage.

"What do you guys here feel after watching this short video? I know you want to ask me why there is no mobile phone in this short story? It's because that glasses replace the mobile phone scene."

"Actually, the phone has been in the protagonist's pocket but has not been taken out. The phone is just providing computing power to the glasses."

"And the connection between everything is the theme of our press conference"

"What connection does everything depend on?, network cable? No, that's too contrary to the signal? That's right! But what about security? Speaking of this, we should introduce our protagonist today, Nebula    OS."

The words Nebula    OS appear on the big screen, and the special effects explode.

"Nebula    OS is a distributed operating system. What is a distributed software system (Distributed    Software    Systems)? It is a software system that supports distributed processing and a system that performs tasks on a multiprocessor architecture interconnected by a communication network. It includes a distributed operating system, a distributed programming language and its compilation (interpretation) system, a distributed file system and a distributed database system, etc.."

"A distributed operating system is responsible for managing distributed processing system resources and controlling distributed program operation. The difference between it and a centralized operating system is in resource management, process communication and system structure.

Distributed programming language is used to write distributed programs running on distributed computer systems. A distributed program consists of several program modules that can be executed independently, and they are distributed on multiple computers in a distributed processing system and are executed simultaneously. Compared with centralized programming languages, it has three characteristics: distribution, communication and robustness.

A distributed file system has the ability to perform remote file access and manage and access files distributed on the network in a transparent manner."

"Simply put, it modularizes all hardware, and it can be used on any computer with computing power, and it is extremely powerful."

"If you have two mobile phones, you want to use A mobile phone to control B mobile phone to take pictures of the A mobile phone you are holding. It is difficult to implement this step at the existing system level, but installing Nebula    OS system does not have this trouble, just one thing."

The major Internet companies in the audience couldn't help but stand up and applaud.

"Everyone knows that the new system has no software and no developers is a blank space. For this reason, I have invited personnel from major Internet companies."
